I guess in the mean time, let your service advisor know to check the AC unit for the collapsed hose as mentioned in the thread and see if it takes you anywhere.

1. Does the sound happen when it is humid and what is the ambient temperature?
2. How frequent this sound occurs?
3. Does the sound comes and goes?
4. Any chance that you can open the hood and hear if the sound is louder when you place your recording device near certain components?
5. Try pushing on components as well.
6. Ignore step 4-5 if it is coming from beneath the engine.
